Comments on August 2006
After the record-breaking July, we returned to normality in August. Indeed, the mean maximum temperature was exactly average, and only a higher than normal mean minimum allowed the mean air temperature to be a little above average. Rainfall too was just about average. It was, however, a very dull month indeed: only August 1912, with a measly 57 hours, has been duller in August since records began in 1882.
